Gettysburg Series – The Sachs Covered Bridge was built around 1854 at a cost of $1,544. On July 1, 1863, the bridge was crossed by the two brigades of the I Corps of the Union Army heading towards Gettysburg. The III Corps also crossed the bridge heading to the Black Horse Tavern. Four days later, the majority of General Robert E. Lee’s Army of Northern Virginia retreated over the bridge after the Union victory in the Battle of Gettysburg.
